Carbon fiber, glass fiber, aramid fiber adhesive strengthening technology of carbon fiber, fiberglass, aramid fiber is a fiber as the reinforced material, synthetic resin as basic material compound and become a kind of engineering materials. For reinforced concrete or steel wire mesh concrete beam, slab, column, shell, truss structures such as paste, after reinforcement component before the carrying capacity of the reinforcement has increased significantly.

Enlarging section reinforcement technique adopts reinforced concrete or grout material increase the cross section area of the original concrete structure is used to improve the bearing capacity of structure. This technology can make the new and old parts good combination, forming a new force as a whole.

Chemical plant steel bar and concrete technology has been widely used in practice, it can solve not obligate anchor bar component on the new component problem, planting-bar technique can be easily embedded in various types of steel in concrete, new old component connection. Companies have different bar diameter and the anchor depth, different aperture of experimental research. The results showed that planting bar on C30 concrete, drawing limit damage load related to steel, steel anchor diameter deep, has no obvious relation with the aperture.

Concrete structures stick steel sticking steel strengthening technique of concrete structure, namely USES the high strength structure adhesive steel plate and concrete structure firmly stick together, to form the overall structure of the compound, transfer stress effectively, thus combining bearing as a whole. Structure can restore or improve the bearing capacity, maintain or increase the strength and stiffness.

Cracks, defects of grouting technology of concrete and masonry structure crack may be produced due to various reasons, especially the stress deformation cracks or temperature stress crack, such as not to governance will cause serious harm. Company has completed hundreds of projects of crack filling defect mending, governance through various types of different reasons of cracks.

Extension-story perfusion extension-story injecting reinforcement reinforcement technology, is on the basis of dry type steel and stick steel was improved, the plus an integral steel better with the original structure, joint force.

Prestressed reinforcement technique by external pre-stressed force after or poles stress changes the structure internal force distribution and reduce the original structure stress level, to reduce the peculiar to the general reinforcement structure stress hysteresis.

The strengthening technology with wire mesh wire mesh by adhesive strength and bending strength excellent polymer mortar and the original structure to form a whole. This method can make the rigid increased the load resistance, and can prevent the durability decreased as a result of polymer mortar weathering. The reinforcement method in a certain extent, have the effect of reinforced concrete composite shear wall, the structure bearing capacity and earthquake resistance can be obtained are greatly improved.

Add layer reconstruction technology building flat roof heat preservation and heat insulation performance is poor, can use ping change slope. When expanding construction area also can be used to calculate the original wall body and foundation reinforcement after add floor: mainly by steel roofing, increased wall column, the new do, increasing the roofing waterproof way.
